The excess coating liquid scraped and discharged can enter the first collection area 13 on the collection hopper 2 for collection, and can be specifically discharged from the liquid discharge pipe 24, avoiding the waste of the coating liquid and having the effect of energy-saving use.

[0048] When it is necessary to remove impurities and dust from the surface of the support roller 1, at this time, the support roller 1 rotates clockwise. At this time, the dust and impurities on the support roller 1 are scraped and discharged by the scraper 11 and fall into the second collection area 14 on the collection hopper 2 for collection. And the exhaust fan 22 operates for a certain exhaust operation, facilitating the inhalation of the dust and impurities into the area of the second collection area 14, avoiding the offset and dropping of the impurities during scraping, and the arranged slag discharge door 23 can realize the discharge of the impurity dust.
